-.SH NOTES
-PSSP (Print Server Security Protocol) is an authentication protocol
-carried out through postscript printer queries to the print server. Using
-PSSP requires LaserWriter 8.6.1 or greater on the client mac. The user
-will be prompted to enter their username and password before they print.
-It may be necessary to re-setup the printer on each client the first time
-PSSP is enabled, so that the client can figure out that authentication is
-required to print. You can enable PSSP on a per-printer basis. PSSP is
-the recommended method of authenticating printers as it is more robust
-that CAP-style authentication, described below.
-.LP
-CAP-style authentication gets its name from the method the CAP (Columbia
-APpletalk) package used to authenticate its mac clients' printing. This
-method requires that a user login to a file share before they print.
-.B afpd
-records the username in a temporary file named after the clients
-Appletalk address, and it deletes the temporary file when the user
-disconnects.
-.B papd
-gets the username from the file with the same Appletalk address as the
-machine connecting to it. CAP-style authentication will work with any
-mac client. CAP-style authenticated printing is a compile-time option for
-netatalk. If both CAP and PSSP are enabled for a particular printer, CAP
-will be tried first, then it will fall back to PSSP.
-.LP
-
-The list of UAMS to use for authentication (specified with the 'am'
-option) applies to all printers. It is not possible to define different
-authentication methods on each printer. You can specify the list of UAMS
-multiple times, but only the last setting will be used. Currently only
-uams_guest.so, uams_passwd.so, and uams_pam.so are supported as printer
-authentication methods. The guest method requires a valid username, but
-not a password. The passwd and pam methods require both a valid username
-and the correct password.

-answers configuration and font queries from printing clients by
-consulting the configured PPD file. Such files are available from
-Adobe, Inc, via anonymous ftp from ftp.adobe.com in /pub/adobe/PPDfiles
-(ftp://ftp.adobe.com/pub/adobe/PPDfiles), or from the printer's
-manufacturer. If no PPD file is configured,
-.B papd
-will return the default answer, possibly causing the client to send
-excessively large jobs.

-.SH CAVEATS
-.I papd
-accepts characters with the high bit set (a full 8-bits) from the clients,
-but some PostScript printers (including Apple Computer's LaserWriter family)
-only accept 7-bit characters on their serial interface by default. You will
-need to configure your printer to accept a full 8 bits.
